SPECIFICATION forming part of Letters Patent Ito. 693,604, dated February 18, 1902. Application Bled January 26, 1901. Serial NOAILSZO. (No model.)

To all whom t may concern:

Be it known that I, HOMER WARREN Hovvn, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Registering Devices for Printing-Presses; and I do hereby declare that the following is a full, clear, and eXact description thereof, reference bein had tothe accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention embracescertain improvements in printing-presses of that class embracing an impression-cylinder and a recip rocating type-bed or part which carries or sup ports the type and in which said cylinder and type-bed are adapted to be moved toward each other at the time each impression is made and are separated at other times.

This invention relates more specifically to means for keeping a record of the total number of strokes of the press or operations thereof which occur in the usualkrunning of the same, whether impressions are made or not, and also the number of movements of the mechanism to bring the typebed and the impression-cylinder into and out of printing engagement, whereby one may readily determine-the number of ineffective operations of the press, as well as the number of impressions inade, and thereby by subtraction ascertain the number of times the feeder has failed to feed a sheet of paper to such press or otherwise missed impressions.

This `invention consists in the matter hereinafter set forth, and more particularly pointed out in the appended claims.

The invention is herein shown as applied to a printing-press having the general construction of the press shown in United States ert Miehle Octobere, 1898, said press embracing a reciprocating type-bed and a continu` above the bed and adapted to be moved bodily toward and from the bed and which makes two rotations for each complete reciprocation of the type-bed and is moved bodily toward and from the type-bed to bring the type into movement of the latter in one direction and to allow the type to pass freely beneath the cylinder without Contact therewith lin the Amovement' of the type-bed in the opposite direction, and means for holding the cylinder of the press out of contact at will.

In the drawings, Figure 1 is a side elevation of the central part of a printing-press provided with my invention. Fig. 2 is a detail side view, with part-s in section, of the lower part of the press at the side thereof opposite that shown in Fig. l, showing operative parts of the press there located. Fig. 3 is a detail side elevation of one of the registering devices, showing the casing therefor in section. Y

In said drawings, A indicates a bed-casting, B one of the main vertical side pieces of the machine-frame, and C-one of the horizontally-arranged frame-pieces which are arranged parallel with said bed-casting A and which afford support for the reciprocating type-bed.

rE is an impression-cylinder located transversely above the type-bed and connected therewith so as to make two or more rotations duri'ng each complete reciprocation of bed is given a reciprocatory motion, as in the printing-press above referred to, said connections being such that the shaft makes one complete rotation during a complete recipro- Vcation of the bed, and being continuously moved during the operation of the press.

I designates a horizontal transverseV rockshaft, which is mounted in suitable bearings in the vertical frame members. Said shaft is adapted to be rocked in its bearings to depress the cylinder against the action of the spring G by means of suitable. connections with the rotary shaft II, such connections consisting in this instance of an arm I', mounted yIoo loosely on the end of the rock-shaftl, a cam- Wheel Il' on the shaft H,provided With a camgroove, Which is engaged by said arm of the rockshaft, and a dog I, pivoted to the outer end of the arm I' and adapted to engage a radialarm I2, rigidly attached to said rockshaft. With this construction said shaft I is rocked in its bearings once during each rotation of the cam and each complete reciprocation of the bed. A tripping mechanism is employed, which acts to throw said dog J out of engagement with the arm ofthe rock-shaft, so that the movement of said dog will have no effect on the rock-shaft, such tripping mechanism being employed to enable the operator to prevent the depression of the impression-cylind er at any time desired-as, for instance, when no sheet is to be fed to the press. Said tripping mechanism consists of a rock-shaft L, to one end of which is attached a foot-lever L' and to the other end of which is rigidly attached a cam orarm L2, which is adapted, when the shaft L is rocked, to lift the dog J out of engagement with the radial arm I2 of the rock-shaft l, as set forth in the above-mentionedpatent. Said foot-lever L' is desirably connected with a footpiece L3 in posit-ion to be accessible to the operator, and the shaft is normally held in position to hold the outer end of the cam-arm depressed by means of a coiled spring L1.

Referring now to the application of my invention to a printing-press of the character thus brieiiy described, these parts are constructed as follows: M designates a registering device of common form, which is located conveniently on a shelf c, attached to one of the uprights D. Said registering device is adapted for actuation from the rotary shaft H, and, as herein shown, is connected by means of a connecting-rod M' with a rocking dog h, which is pivoted on a stud h', attached to the outer face of the frame side piece B. Said dog 7L is provided with a stud h2, which engages a cam H2, attached to the rotative shaft H. The stud h2 is held in position to engage the larger part of the cam by means of a spring h3, and a stop h4 on the frame serves to limit the movement of the dog under the action of the spring, so that the said stud h2 is in contact with the cam during a part only of its rotation. The said cam, in connection with its associated spring, gives movement to the stud h2 inwardly and outwardly at each complete rotation of the shaft H, so that the rod M' will be given vertical movement necessary for actuating the registering device M at each operation of the press by which an impression is made. The rod M' is attachedat its upper end to an actuatingarm M2 on the registering device. A spring M3 is interposed between the upper end of the rod or wire M' and the said actuating-arm of the registering device, said spring being provided for the purpose of preventing sudden jars coming upon the actuating-arm and the mechanism of the registering device.

Said registering device may obviously be otherwise actuated from the type-bed or its actuating mechanism-as, for instance, its actuating-arm may be arranged to be directly engaged by the bed or a part carried thereby. Said registering device M, connected as described, serves to register each rotation of the shaft H, and consequently each complete reciprocation of the type-bed, so that the dial of said device at any given time Will indicate the number of complete oscillations of the press. I propose also to provide the press With a registering device which is adapted for actuation by a part of the printing-press which is actuated only at the time the cylinder is moved toward the type-bed, so that not only will the number of operations of the press be recorded, but also the number of its effective operations, or those in which the cylinder is brought into printing position with relation to the type-bed. For this purpose I provide a second register N, which in the type of press shown will conveniently be connected with the rock-shaft I, which acts to depress the cylinder. Said second register N is located conveniently on a shelf or ledge d', attached or made integral with the top cam piece D', attached to the uprights D. Said registering device is actuated from the rock-shaft through the medium of a connecting rod or wire N', connected at its lower end with a dog I', which is pivoted on the side of the frame and is provided with a stud I3 on the outer end of the rock-shaft I and at its upper end with an arm N2, connected with the mechanism of the registering device. A spring N3, similar to the spring M3, is interposed between said connecting rod or wire and actuating-arm of the registeringdevice for the same reason as before explained. The registering device N, connected as thus described, will record each movement of the rock-shaft as the same is actuated through the medium of the cam-Wheel H', and if a sheet of paper be fed to the press during each operation of the same the record of said registering device N will correspond with the record of the registering device M. If, however, for any purpose the action of the impression-cylinder be interrupted through the medium ofthe tripping m echanism described, the rock-shaftI being at such time at rest, the registering device N will not be actuated, and its record will remain the same, while `each succeeding rotation of the shaft H and Itwill be seen, therefore, that' IOO IIO

records before the person who has charge of said press it willbe easy to determine the number of ineffective operations of the press, or those in which no impression Was made, such result being obtained by deducting from the number representing the Whole number of movements of the press the number which represents the effective operations thereof. This, as will be readily appreciated by persons acquainted with this art,is of great importance, as it enables the superintendent of a Whether a press is running either by visual observation or 'by the sound made by the press he has been unable tovkeep informed as to the regularity with which the press is fed, the diligence of the feeder, or the number of impressions made in a given time as compared with the possible capacity of the press, as he has had no convenient or ready means of ascertaining the number of operations which have been ineffective or which have not resulted in the printing of a sheet.

As before stated, I contemplate using my invention on all types of printing-presses which contain a continuously-actuated part which operates one of the principal elements of the press-as, for instance, the devices by which the impressioncylinder and type-bed are brought into and out of engagement when making impression or printing and which is connected With the other of said main elements to bring the same into its operative or printing position, and I do not therefore Wish to `be limited withl respect to the application of my invention to the special form of press illustrated. v

It is desirable in the use of a registering device of the character described that the same should be protected from interference by the Workman operating the press. I therefore "provide in connection with the parts described inclosing means for the several parts described,as follows: O indicates a metal casing or inclosure which is attached to the side of the main frame of the press and surrounds the cam IrI2 and dog h and also the end of the rock-shaft I, said casing being constructed to completely inclose said parts. Casings P and Q are also arranged to inclose or surround the registers M and N, said casings being provided With openings through which the indicating-numbers of the registers can be seen and with outwardly-projecting parts 19 and q inclosing the actuating-arms M2 and N2 of said registers. To inclose and protect the connecting-rods M and N', metal tubes R and S are attached at their lower ends to the casing O and at their upper ends to the outwardly-projecting parts p q of the casings P and Q.

The parts of the registering devices being covered and pivoted by the vinclosures described their operation cannot be affected or interfered with by the operator of the press, and the Vsaid registering devices are therefore entirely under the control of the owner of the establishment or foreman having charge of the press.

I claim as my invention* 1. In a printing-press, the combination with a continuously-movable part which actuates one of the principal elements of the press, and an intermittingly-movable part which is connected with another principal element of the press, of a 'registering device actuated by said continuously-movable part, and a second registering device actuated by said in termittinglvmovable part.

2. In a printing-press, the combination With a reciprocatory type-bed, a rotative impression-cylinder, and means for moving said cyl inder toward and from the said bed, of aregistering device which is connected with and actuated by saidV bed or its actuating mechanism, and a second registering device which is connected with and actuated by the means for moving said cylinder toward the type-bed.

3. In a printing-press, the combination with a continuously-movable part which actuates one of the principal elements of the press, and an intermittingly-movable part which is connected with another principal element of the press, of a registering device actuated by said continuously-movable part, a second registering device which is connected with said intermittingly-movable part, and a cas ing or inclosure surrounding both of said reg istering devices and the moving parts through which they are connected with said continuL ously and intermittingly movable parts of the press.

l In testimony that I claim the foregoing as my invention I aiiix my signature, in presence of two Witnesses, this 8th day of January, A. D. 1991.
